At the end of the nineteenth century, the wolf Canis lupus was extinct in Hungary and in recent decades has returned to the northern highland area of the country. The diet of wolves living in groups in Aggteleki National Park was investigated using scat analysis (n = 81 scats) and prey remains (n = 31 carcasses). Throughout the year wolves (average, minimum two wolves per year) consumed mostly wild-living ungulates (mean percent of biomass consumed, B% 97.2%; relative frequency of occurrence, %O 74.0%). The wild boar Sus scrofa was the most common prey item found in wolf scat (%B 35.6%) and is also the most commonly occurring ungulate in the study areas. The second most commonly occurring prey item in wolf scat was red deer Cervus elaphus (B% 32.8%). Conversely, prey remain analyses revealed wild boar as the second most commonly utilised prey species (%O 16.1%) after red deer (%O 67.7%). The roe deer Capreolus capreolus that occurs at lower population densities was the third most commonly utilised prey species. The importance of low population density mouflon Ovis aries, livestock and other food types was low. The results are similar to those found in the northern part of the Carpathian Mountains.

Game damage to agriculture represents one of the most important and most frequent human–wildlife conflicts worldwide. In Hungary and in the other European countries, damage caused by wild boar (Sus scrofa) and red deer (Cervus elaphus) is the most significant. The volume of damage is correlated with the population density of the game species, however, not exclusively. Since the growing expansion of wild ungulates is a general tendency in Europe, increasing conflicts can be envisaged. The objective of our study was to assess the possible relationships between the amount of agricultural game damage and big game population density considering some other factors (e.g. habitat structure, sown area of cultivated plants) by analysing wildlife management and land-use statistics for the 19 counties of Hungary from 1997 to 2008. According to the results, crop damage positively correlated with the population density of red deer and wild boar, with the length of forest edge, and the proportion of the sown area of maize. According to the regression model, these factors could be accountable for 74.2 % of the total agricultural game damage.
